1 Total Knee Replacement
(Total Knee Arthroplasty)

2 Why Perform a TKR? Relief from…
Chronic pain Deformities Stiffness Decreased ROM Loss of ability to perform daily tasks Considered when non-surgical attempts at pain relief have failed Physical therapy Cortisone shots

3 Arthritis Inflammation, pain, and stiffness of the joints
Main cause of chronic knee joint pain and disability in patients Over 100 various types 3 most commonly result in in a TKR Osteoarthritis Rheumatoid arthritis Post-traumatic arthritis

4 Forms of Arthritis Osteoarthritis (OA) Rheumatoid Arthritis (RA)
Post-Traumatic Arthritis Age related (50+) Cartilage softens and wears away The bones rub together causing the pain Bone spurs may form Synovial membrane becomes inflamed Damages cartilage Results in pain & stiffness Most common after a serious injury Fracture and ligament tear damage the articular cartilage over time Results in pain and limited function

5 1. Making the Incision The incision is cut along the top of the knee joint. Minimally invasive 4-6 inches long Normal 6-10 inches long

6 2. Exposure of the Knee Joint
Patella and patella tendon are exposed They are rotated outward to the side of the knee joint A full view of the knee joint is obtained

7 3. Removal of Bone Spurs The area of the knee, which will not be removed is checked for bone spurs. The spurs are removed with a rongeur, if present. Bone spurs are due to bone on bone rubbing over time.

8 4. Preparation of the Femur
Jigs are secured to the femur Damaged bone is removed from femur with the bone saw Femur is shaped to fit properly with the femoral component

9 5. Preparation of the Tibia
Jigs are secured to the tibia Damaged bone is removed from tibia with the bone saw Tibia is shaped to fit the tibial plate properly

10 6. Preparation of the Patella
It is only sometimes necessary to cut the patella If it is necessary… The top of the patella is cut with the bone saw It is cut to fit the plastic patella component If it is not necessary The patella is left alone

11 7. Fitting of the Femoral Component
The femoral component is hammered into the femur Bone cement is used to secure the prosthesis

12 8. Fitting of the Tibial Tray
The tibial tray is hammered into the tibia Bone cement is used to secure the prosthesis to the flattened tibia

13 9. Fitting of the Patella Component
The patella component is secured to the prepared patella with bone cement

14 10. Hardening of the Cement
Any cement left surrounding the prosthetic components is cleared away The cement is left to dry for about five minutes or until the leftover portions are ensured to have hardened.

15 11. Placement of the Polyethylene Component
Polyethylene medial component is snapped into the top of the tibial tray Serves as a replacement for the missing cartilage

16 12. Knee Trial Alignment and fit are confirmed
Flexion and extension are tested Leg lengths are compared

17 13. Closing of the Incision
A drain is placed if necessary Muscles are sewn with absorbable sutures Skin is fasted with either Absorbable sutures Normal sutures Derma-bond Staples

18 14. Bandaging and the CPM The leg is wrapped with an ACE bandage
Removed 24 hours post- op CPM is placed on the patient Prescribed for 6 hours a day

19 Recovery Wound Care Swelling and drainage must be watched carefully
Keep incision site clean and dry If staples or non-dissolvable sutures are used they must be removed days post-op

20 Recovery Pain Management PCA prescribed for 24 hours via
Spinal epidural IV injection Oral pain killers are prescribed to manage pain when PCA is removed Wean the patient from narcotic analgesics to non-steroidal anti-inflammatories

21 Recovery Rehabilitation Post-op hospital setting addresses:
Bed mobility CPM Walking with assistive devices Increasing ROM Post acute care addresses: Muscle strengthening Flexion and extension exercises Return to sport/activities

22 Recovery: Follow Up Appointment is held 6-8 weeks post-op
Review the incision and healing process Check for infection Ensure increase in ROM Continue follow ups appointments periodically for 1 year post-op

24 Reflective Letter This PowerPoint presentation was created in order to educate members of the healthcare team, including residents, nurses, etc. on the total knee replacement procedure. Having a background of the procedure can enhance the post-operative care given to the patient by the nursing staff. The overview of the procedure also serves as a suitable refresher for the resident, physician assistant, or operating room nurse that will be aiding in the procedure. The audience consisting of fellow healthcare professionals allows the PowerPoint to use medical terminology and abbreviations without explanation, keeping the text concise and to the point. The presentation could be accessed through a learning portal, requiring these individuals to review the PowerPoint, or through an in-service presented to the audience. The design was chosen to reflect the hospital atmosphere of whites and light blues, while preventing the background from becoming distracting. Pictures were placed generously throughout the presentation in order to compliment the text and appeal to both visual and verbal learning styles. In order to enhance the ability of the audience to effectively follow the information, the content is structured chronologically. Brevity was used in the content of the presentation, omitting all unnecessary information to keep the attention of the medicinal professional audience addressed.

25 Note This piece fits into my professional portfolio, because it shows future employers my ability to communicate effectively with fellow professional colleagues. By showcasing my aptitude to write with brevity and clarity addressing these professional colleagues I am further enabling potential employers to better understand my skills in writing and communication with these professionals.
